In fact it appears where you click. If you create a button with 'uisetcolor' as callback, the dialog box appears near the button. And if the button is near the screen borders, the dialog box is not displayed entirely, making it sometimes impossible to move!

As I mentioned, it may be different for that new colour picker, which I rejected. I created my own colour picker in the end, but I still find it useful to have uisetcolor sometimes which is why I set it to use the old version. It is a hidden preference in code rather than a visible one, as described in a comment to the answer in the linked thread.

Not a direct solution of your problem, but maybe it helps to use one of the alternative color choosers: https://undocumentedmatlab.com/blog/color-selection-components
cc = javax.swing.JColorChooser;
[jColorChooser,container] = javacomponent(cc,[1,1,450,325],gcf);
jColorChooser.getColor
Or
cp = com.mathworks.beans.editors.ColorPicker;
[jColorPicker,container] = javacomponent(cp,[1,1,400,200],gcf);
Or:
options = 0;
icon = 0;
cp = com.mathworks.mlwidgets.graphics.ColorPicker(options,icon,'');
[jColorPicker,hContainer] = javacomponent(cp,[10,220,30,20],gcf);

Thx Jan. I know Yair's site. It just seems to be a bug to me. I will use Java ColorPicker if this bug is not fixed soon.

@Luc: Did you write a bug report to MathWorks already? Usually bugs are fixed with new versions and maybe the code of R2018a is not closed yet.
